Map & Tracking Station Maneuver Node Order Issue

[schlosrat]

Reported Version: v0.1.3.2 (latest) | Mods: none | Can replicate without mods? Yes 
OS: Win 11 Pro | CPU: i9-9900K | GPU: AMD Radeon RX 6800 XT | RAM: 32GB

 

When creating a maneuver node, if the new node is created on the active vessel's orbit at a point earlier than what was previously the first node, then the old first node (which is now the second node) is not treated as being "on the trajectory" (IsOnManeuverTrajectory == false, ManeuverTrajectoryPatch == null), and consequently when changes are applied to the new first node these changes do not cause the location for the second node to be correspondingly updated. If the nodes are created in the opposite order (the earliest node is created first), then the second node is correctly set to be "on the trajectory" (IsOnManeuverTrajectory == true, ManeuverTrajectoryPatch == patch resulting from first node), and any changes to the first node do correctly result in changes to the location of the second node.

See the short video below for a simple example of both scenarios described above.

Observed Behavior: When a new node is placed before any other existing nodes, the locations of the subsequent nodes are not correctly updated when the new first node is edited.

Expected Behavior: When a new node is placed on an orbit prior to any existing nodes, those prior nodes are updated to be on the correct trajectory such that any changes applied to the new first node correctly impact the locations of the subsequent nodes.

@schlosrat I replaced your link with the uploaded video. At a guess that won't work properly until they add the 'next orbit' feature at some point like KSP1 has.

On a different issue, I was wondering if you have been experiencing UI flickering with your RX 6800XT?

Thanks @Anth12. I think the problem is simpler than that and could be solved today. For example, I've got a dev version of Node Manager that I'm using with Maneuver Node Controller and Flight Plan to implement a fix. These are mods, obviously, but they just call what's already there in the game. So far, I've got it where I can create the earlier node after the later one, and the later one will follow the earlier one perfectly... after you give the earlier one any adjustment. It's not completely perfect yet, as when you create the earlier node the later one briefly seems to still be on the original orbit. I think I can solve that, and plan to before I release the next version of Node Manager.

So, I think if it can be solved today with a mod, then it could be fixed in the game without needing new features.

Regarding the RX 6800XT, yes I do get flickering. It's annoying, but it's also not present all the time. I wish I knew what brings it on, but I don't. When it's there, it's always there and doesn't go away any time soon even with exiting and relaunching the game.

Simpler than I thought then. Next, I guess is getting the bug report higher up using upvotes to get the developers attention. I know it will be fixed eventually, but that will be how to get it fixed sooner.

It's not present all of the time? That is interesting. I bought a RX 6600 recently. Maybe if I have some solid game play with it (it's on my older computer) I can figure out what the difference is. Thanks for the information.

Here's a video demonstrating that this can be solved today with mods. This is my first shot at fixing it, so it's not optimized or ideal, but it does in fact work. If mods can fix it then devs can fix it - and likely much better!

That flight plan mod can do transfer windows? I might take a look at that.

There are all sorts of things it does! It’s basically a port of parts of MechJeb2, mainly the maneuver planer parts. The interplanetary transfer part is straight up MJ. I’m still working on the Advanced Interplanetary transfer though. The basic version doesn’t cope well with different orbital planes, so the results are sub optimal and you’ll need a course correction - but I’ve used it to get to Dres that way, so it does work.

Thanks for the information. Sounds cool. I will take a look at it when I have a chance. I thought there was only one mod that could do transfer windows and it was out of date.
